... Scientists are keen to learn all the SNPs and record them in the equivalent of a dictionary. No one knows for sure how many SNPs will be found, but already over 38 million unique and validated SNPs have been identified. Many more rare SNPs are likely to be found over the next few years as more and m ...

Tag SNP



A tag SNP is a representative single nucleotide polymorphism (SNP) in a region of the genome with high linkage disequilibrium that represents a group of SNPs called a haplotype. It is possible to identify genetic variation and association to phenotypes without genotyping every SNP in a chromosomal region. This reduces the expense and time of mapping genome areas associated with disease, since it eliminates the need to study every individual SNP. Tag SNPs are useful in whole-genome SNP association studies in which hundreds of thousands of SNPs across the entire genome are genotyped.
